技术领域Technical field
本申请涉及散热技术领域，特别涉及一种散热器及设备。This application relates to the field of heat dissipation technology, and in particular to a radiator and equipment.
背景技术Background technique
随着移动通信基站热耗、集成度持续提升，产品面临高功率、高热密度的散热挑战。为了满足冰雪暑热、风沙盐雾等各种户外恶劣环境的运行要求，户外设备散热方式通常采用可进行自然散热的散热器，避免各种有源散热部件失效而导致的基站设备过热宕机，例如风扇故障等。As the heat consumption and integration level of mobile communication base stations continue to increase, products face heat dissipation challenges of high power and high heat density. In order to meet the operating requirements of various harsh outdoor environments such as ice, snow, heat, wind, sand, and salt spray, outdoor equipment usually uses radiators that can naturally dissipate heat to avoid overheating and downtime of base station equipment caused by the failure of various active heat dissipation components, such as Fan failure, etc.
散热器通常由散热基板和齿片组成，齿片呈一定间距分布在基板上。热源部件通常贴在散热基板上，通过散热基板把热量传递到齿片，再通过自然对流和热辐射散发到外界环境中。由于散热器的制成材质热阻比较大，当热源部件的热耗较大时，从散热基板与热源部件接触面到散热齿片的齿根通常就有10多度的温差，齿根到齿顶又有几十度温差，散热齿与外部环境之间温差较小，影响了散热器的散热效率。A radiator is usually composed of a heat dissipation base plate and toothed fins. The toothed fins are distributed on the base plate at a certain distance. The heat source component is usually attached to the heat dissipation substrate, and the heat is transferred to the gear plate through the heat dissipation substrate, and then dissipated to the external environment through natural convection and thermal radiation. Since the heat sink is made of a material with relatively large thermal resistance, when the heat dissipation of the heat source component is large, there is usually a temperature difference of more than 10 degrees from the contact surface between the heat sink substrate and the heat source component to the tooth root of the heat sink fin. There is a temperature difference of tens of degrees at the top, and the temperature difference between the heat dissipation teeth and the external environment is small, which affects the heat dissipation efficiency of the radiator.

由于第一热源器件通过通孔与散热模组接触，进而大大缩短了散热模组与第一热源器件的换热路径，提高了散热器的散热效率。Since the first heat source device is in contact with the heat dissipation module through the through hole, the heat exchange path between the heat dissipation module and the first heat source device is greatly shortened, and the heat dissipation efficiency of the radiator is improved.
由于第二热源器件与散热模组通过接触结构间接接触，使散热模组的工质亦可吸收第二热源器件产生的热量。Since the second heat source device and the heat dissipation module are in indirect contact through the contact structure, the working medium of the heat dissipation module can also absorb the heat generated by the second heat source device.

Different from the arrangement in the third direction of the first direction, the at least one through hole and the contact structure are located in the first area, and the second area is used to provide heat dissipation fins.
通孔分布于第二安装面的局部区域而非进行整体挖孔，这样一来，有利于提高主箱体的强度。The through holes are distributed in local areas of the second mounting surface instead of digging holes as a whole, which helps to improve the strength of the main box.
在第二区域设置散热翅片有利于对热源部件对应第二区域的第三热源器件进行散热。由于散热翅片相对两相散热器的成本更低，有利于降低散热器的成本。Providing heat dissipation fins in the second area is beneficial to dissipating heat to the third heat source device corresponding to the second area of the heat source component. Since the cost of cooling fins is lower than that of two-phase radiators, it is beneficial to reduce the cost of the radiator.

The contact structure on the main box can be integrally formed with the main body of the main box during the die-casting process, and the manufacturing difficulty and manufacturing cost are also low. The heat dissipation module does not need to be equipped with a structure that is connected to the heat source component. Instead, the main box is used to support the heat source component to achieve decoupling of the heat dissipation module and the heat source component, which is conducive to simplifying the structure of the heat dissipation module and facilitating the heat dissipation module. The manufacturing of the heat dissipation module enables the heat dissipation module to adapt to more heat source components.

The two-phase toothed plates protrude from the second surface, and a second micro-slit is formed at the intersection between the two-phase toothed plates and the second surface.
需对腔体盖板与两相齿片进行焊接时，可在第一表面、第二表面涂覆焊料。由于突出端与第一表面共同形成的第一微缝的毛细作用，第一表面上融化的焊料会沿突出端与第一表面共同形成的微缝定向流动并堆积形成第一焊缝。由于突出端突出第一表面设置，焊料难以透过突出端的阻拦进入流道口，降低了流道口被焊料堵塞的可能性。When it is necessary to weld the cavity cover plate and the two-phase tooth plate, solder can be coated on the first surface and the second surface.

Since the protruding end protrudes from the first surface, it is difficult for solder to enter the flow channel opening through the obstruction of the protruding end, thereby reducing the possibility that the flow channel opening is blocked by solder.
由于两相齿片与第二表面共同形成的第二微缝的毛细作用，第二表面上融化的焊料会沿两相齿 片与第二表面共同形成的第二微缝定向流动并堆积形成第二焊缝。Due to the capillary action of the second micro-slit formed by the two-phase teeth and the second surface, the melted solder on the second surface will move along the two-phase teeth.

具体实施方式Detailed ways
移动通信基站通常为堆叠式架构，包括散热器、收发信机(TRX)、屏蔽盖、电源、滤波器等多个部件，其中主要散热部件为散热器。散热器包括散热基板和齿片。齿片呈一定间距分布在基板上，考虑防腐、重量、成本等需求，齿片和基板的材料一般都为铝合金，可通过压铸、机加、冷嵌、焊接等工艺来加工实现。基站中的主要热耗部件，例如收发信机、电源都是贴在散热基板上，通过散热基板将热量传递到齿片，再通过自然对流和热辐射散发到外界环境中。Mobile communication base stations usually have a stacked architecture, including radiators, transceivers (TRX), shielding covers, power supplies, filters and other components. The main heat dissipation component is the radiator. The radiator includes a heat dissipation base plate and teeth. The gear plates are distributed on the base plate at a certain distance. Considering the requirements of anti-corrosion, weight, cost, etc., the materials of the gear plates and the base plate are generally aluminum alloy, which can be processed through die-casting, machining, cold embedding, welding and other processes. The main heat-consuming components in the base station, such as the transceiver and power supply, are attached to the heat dissipation substrate. The heat is transferred to the teeth through the heat dissipation substrate, and then dissipated to the external environment through natural convection and thermal radiation.
通常铝合金的导热系数有限，一般为140-210W/(mK)，因而散热器自身热阻较大。当模块和器件热耗较大时，从散热基板与器件接触面到散热齿齿根部通常就有10多度的温差，齿根到齿顶又有几十度温差，散热齿与外部环境间温差较小，无法进行高效换热，散热器散热能力有限，因而如何提升散热器自身热传 导能力，减小散热器自身热阻，对于基站的散热能力提升是至关重要的。Generally, the thermal conductivity of aluminum alloy is limited, generally 140-210W/(mK), so the heat sink itself has a large thermal resistance. When the heat dissipation of modules and devices is large, there is usually a temperature difference of more than 10 degrees from the contact surface between the heat dissipation substrate and the device to the root of the heat dissipation teeth, and there is a temperature difference of several tens of degrees from the tooth root to the tooth top. The temperature difference between the heat dissipation teeth and the external environment It is too small to carry out efficient heat exchange, and the heat dissipation capacity of the radiator is limited. Therefore, how to improve the heat transfer of the radiator itself? Conductive capacity and reducing the thermal resistance of the radiator itself are crucial to improving the heat dissipation capacity of the base station.
其他与移动通信基站散热类似的设备还包括户外电源，小型光伏逆变器等。Other equipment similar to the heat dissipation of mobile communication base stations includes outdoor power supplies, small photovoltaic inverters, etc.
现有散热基板受铝合金导热系数影响，导热能力有限，平面均温能力较弱，不利于高密热耗芯片向四周快速散热，严重制约散热器的散热效能提升。The existing heat dissipation substrate is affected by the thermal conductivity of aluminum alloy, has limited thermal conductivity, and weak plane temperature equalization ability, which is not conducive to rapid heat dissipation of high-density heat-consuming chips to the surroundings, seriously restricting the improvement of the heat dissipation efficiency of the radiator.
虽然通过采用吹胀板可以实现齿片均温，但是对器件布局有明显约束，另外散热器基板到齿片导热路径较长，热阻较大，热性能提升依然有限。Although the temperature uniformity of the tooth blades can be achieved by using an inflated plate, there are obvious constraints on the device layout. In addition, the heat conduction path from the radiator substrate to the tooth blades is long, the thermal resistance is large, and the thermal performance improvement is still limited.

When the local area of the cavity component 30 is heated, the working medium near the heated spot will absorb heat and change from liquid to steam. The steam will diffuse from the cavity component 30 to the two-phase tooth plate 12 under the pressure difference, and then regenerate by releasing heat. It becomes liquid and finally flows back to the cavity component 30 under the action of gravity.
通过工质的气液变化可以实现两相齿片12的快速均温，提高了两相齿片12的等效导热系数，减小了两相齿片12的齿根与两相齿片12的齿顶之间的温差，有效提升两相齿片12整体的换热效率，进而增强了散热器101的散热效率及散热能力。Through the gas-liquid change of the working fluid, rapid temperature equalization of the two-phase tooth plate 12 can be achieved, which increases the equivalent thermal conductivity of the two-phase tooth plate 12 and reduces the distance between the tooth root of the two-phase tooth plate 12 and the two-phase tooth plate 12 The temperature difference between the tooth tops effectively improves the overall heat exchange efficiency of the two-phase tooth plate 12, thereby enhancing the heat dissipation efficiency and heat dissipation capacity of the radiator 101.

由于两相齿片12与第二表面326共同形成的第二微缝的毛细作用，第二表面326上融化的焊料会沿两相齿片12与第二表面326共同形成的第二微缝定向流动并堆积形成第二焊缝503。第二焊缝503与两相齿片12固定连接，第二焊缝503与第二表面326固定连接。Due to the capillary action of the second micro-slit formed by the two-phase tooth plate 12 and the second surface 326, the melted solder on the second surface 326 will be oriented along the second micro-slit formed by the two-phase tooth plate 12 and the second surface 326. Flow and accumulate to form the second weld 503. The second welding seam 503 is fixedly connected to the two-phase tooth plate 12 , and the second welding seam 503 is fixedly connected to the second surface 326 .
